Tieu Coc is a primary school student and plans to participate in the International Math Olympiad. She is 12 years old and has started teaching online since 2022. The first video she shared was how to solve secondary school math problems. Up to now, more and more people are interested in Tieu Coc's online lectures to find the most optimal way to solve problems.

In her teaching videos, Tieu Coc stands in front of a whiteboard, holding a marker pen in her hand. She confidently teaches everything from Geometry to Functions, even Calculus. The content Tieu Coc covers focuses mainly on the difficult problems for first-year students.

In December 2023, Tieu Coc received many thanks for providing the optimal solution to an advanced university math problem. After that, many candidates applied it and achieved results in the graduate entrance exam. "Thank you 'Ms. Coc' for helping me earn 5 more points," said a candidate.

Tieu Coc's special ability in Mathematics comes from her undying passion for this subject since childhood. Through teaching videos, the female student has shared her approach to Mathematics. At the same time, Tieu Coc also pointed out methods on how to study this subject well.

Tieu Coc's mother said that she was the one who encouraged her daughter to record a video sharing her method of improving her math learning ability. This learning method is called the Feynman Memorization Technique. Accordingly, everyone can absorb knowledge better if they apply the 'teach to learn' method.

A person who regularly follows Tieu Coc said: "The knowledge in high school made me have a lot of difficulties. But after watching Tieu Coc's videos, everything became clearer." Some people joked that, even though they are students, they still have to 'rely' on the 12-year-old girl to solve their homework.

Besides, there are still many opposing opinions doubting Tieu Coc's ability. "A genius only appears once in a hundred years, surely behind her must be a hard-working team", one person commented.

Opposing the above thinking, some people said: "The knowledge that Tieu Coc mentioned is relatively difficult. If you do not understand the nature, it is difficult to practice well."

Before Tieu Coc, 5-year-old Du Quach also caused a 'storm' online because he taught Programming in 100% English. Thanks to that, his Douyin account attracted 740,000 followers.

Tieu Coc shares the lecture Finding Hyperbolic Equations:
